Automatic detection equipment for welding defects of copper bar

A copper bar welding defect automatic detection device is sequentially provided with a first screw hole detection station, a first welding seam detection station, a second screw hole detection station, a product appearance detection station and a second welding seam detection station in advance, and comprises a multi-station rotating disc and a rotation driving assembly, and a plurality of jig seats arranged at equal angles are arranged in the circumferential direction of the multi-station rotating disc; the rotary driving assembly is connected with and drives the multi-station rotary table to rotate, so that the jig seats are sequentially moved to the stations through rotation of the multi-station rotary table, and welding defects of welding seams at the two ends of the sleeve and in screw holes in the two ends can be detected at a time. The rapid integrated welding quality detection scheme can meet the requirements of welding quality, size detection, thread quality and foreign matter residues, is rapid and
